This operation is carried out to treat otosclerosis, a disorder in which the stapes bone in the middle ear becomes immobilized by bony overgrowth, causing hearing loss. Under local or general anaesthesia, parts of the stapes are removed and replaced by a prosthesis. Stapedotomy is usually successful, but there is a small risk that hearing may deteriorate further.
